ROTARY Klin (Capacity 400 TPD To 3000 TPD)

The Rotary Klin made from MS Steel Plate, and Lined with firebrick. The Klin slopes slightly (1-40) and slowly rotates on its axis at between 30 and 200 revolutions per hour. Rawmix is fed in at the upper end, and the rotation of Klin causes it gradually to move and go down to the other end of the Klin. At the other end fuel, is blown in through the burner, producing a large concentric flame in the lower part of the Klin. As material moves under the flame, it reaches its peak temperature, before dropping out of the Klin into the cooler. Air is drawn first through the cooler and then through the Klin for combustion of the fuel. In the cooler the air is heated by the cooling clinker, so that it may be 350 to 850 0C before it enters the Klin, thus causing intense and rapid combustion of the fuel.

Rotary Klins run 24 hours a day, and are typically stopped only for a few days once or twice a year for essential maintenance. This is an important discipline, because heating up and cooling down are long, wasteful and damaging processes. Uninterrupted runs as long as 18 months have been achieved.
